Optically transparent water oxidation catalysts based on copper nanowires.
Let the light shine through: A transparent film of copper nanowires was transformed into an electrocatalyst for water oxidation by electrodepostion of Ni or Co onto the surface of the nanowires. These core-shell nanowire networks exhibit electrocatalytic performance equivalent to metal oxide films of similar composition, but are several times more transparent.
متن کاملRecent studies of the copper-molybdenum antagonism.
The biological antagonism between copper and molybdenum was discovered when cattle grazing pastures high in Mo were found to develop a syndrome characterized by diarrhoea, growth retardation, anaemia and achromotrichia, which could be prevented by administering Cu. This syndrome was subsequently reproduced in non-ruminants, but further studies revealed important differences in the nature of the...

متن کاملCatalytic decomposition of CF4 over copper promoted mesoporous catalysts
A series of mesoporous catalysts (MCM-41) promoted by copper oxide nanoparticles were prepared by the co-precipitation method and tested for the decomposition of carbon tetrafluoride (CF4). The addition of copper oxide nanoparticles to MCM-41 led to an improvement in the catalytic activity for CF4 decomposition. The catalyst was the most active around 5 wt% copper oxide added to MCM-41. Methods...
متن کاملEffect of Surface Copper Species on NO + CO Reaction over xCuO-Ce0.9Zr0.1O2 Catalysts: In Situ DRIFTS Studies
In this work, the activity of xCuO-Ce0.9Zr0.1O2 catalysts for the reaction of NO + CO was investigated. Especially, in situ DRIFTS was applied to investigate the surface species under the adsorption of NO and/or CO and the reaction of NO and CO to understand the key intermediates species and reaction process of NO + CO. The results suggest that the copper oxide species are well dispersed on the...
